Star Trek has never been entirely consistent about its maps in or out of canon. I don't recall TNG ever showing us anything in detail, and if you're going by Okudagram stuff on monitors, then you'll have to canonize a ton of little in-jokes, too.

Besides, STO is a non-canon property along with everything else that isn't on a TV or movie screen, so as long as it meets with CBS approval, Cryptic could put Archer IV in Gamma Orionis if they really wanted to. A moot point anyway, since this Archer is a different system entirely according to the tooltip text.
